Sistem Pakar Pemupukan Kelapa Sawit Menggunakan Metode Forward Chaining

Abstract

<em>Oil palm smallholders require knowledge of fertilization because the fertilization is an influential factor in the productivity of fresh fruit bunches. On the other hand, the oil palm smallholders generally don’t have fertilizer expertise and they face a difficulty in determining good fertilization (good in type, dosage, time and manner) based on various literatures. Therefore, a simple application that can provide recommendations for palm oil fertilization is developed. The recommendations are based on expert knowledge that have been written in various literatures. Like an expert system, the application is designed by compiling knowledge base, constructing an inference engine and creating a prototype. The knowledge bases, that are facts and rules, are prepared using rule-based reasoning approach, the inference engine is compiled using forward chaining methods and the prototype is made using a visual basic application in a spreadsheet application. The application design uses facts of plant varieties, phases or age of plants, soil types, nutrient deficiency in soil and plants, rainfall, fertilizer content, and nutrient properties (synergies or antagonist) on fertilizers. The Applications made capable of providing fertilization recommendations by conducting forward chaining based on data-given facts and rules that have been made on the knowledge base.</em>

Micronutrients Concentrations in Leaves of Oil Palm Trees Fertilized with Phosphorus, Potassium, and Magnesium

“…Natural causes, such as soil genesis and weathering, are the main causes of low soil fertility, especially in tropical and subtropical regions, due to high temperatures and rainfall levels, which accelerate the leaching of nutrients (Lopes & Guilherme, 2007). The nutrients available in tropical soils are insufficient to meet the nutritional demands of cultivated plants, requiring soil fertilization (Priyandari et al, 2017).…”

Tingkat Akurasi dalam Mengidentifikasi Penyakit Telinga Menggunakan Metode Forward Chaining dan Certainty Factor

“…Metode Forward Chaining menggunakan teknik inferensi yang dimulai premis yang berisikan fakta pengetahuan [13] [14]. Fakta akan dicocokkan sehingga menghasilkan kesimpulan akhir [15]. Metode Certainty Factor digunakan untuk mengakomodasi ungkapan meragukan yang sering terjadi saat pakar menganalisa informasi [16][17][18] [19].…”
